Antioxidant compositions

ABSTRACT

AN ANTIOXIDANT COMPOSITION FOR OILS AND FATS PARTICULARLY THOSE USED FOR FRYING IS RETAINED IN THE OIL OR FAT EVEN AFTER MANY FRYING AT HIGH TEMPERATURES. INCLUDED IN THE COMPOSITION ARE (A) ABOUT 60 TO 99% BY WEIGHT OF THE COMPOSITION OF AN ANTIOXIDANT SELECTED FROM THE GROUP CONSISTING OF MONO-TERTIARY-BUTYLHYDROQUINONE, A GALLIC ACID ESTER SELECTED FROM PROPYL, OCTYL OR DODECYL GALLATES; AND BLENDS OF THESE ANTIXODANTS WITH BUTYLATED HYDROXYANISOLE AND BUTYLATED HYDROXYTOLUENE; (B) 0 T0 34% BY WEIGHT OF THE COMPOSITION OF AN ORGANIC ACID SYNERGIST SELECTED FROM THE GROUP CONSISTING OF CITRIC ACID, ASCORBIC ACID, TARTARIC ACID, FUMARIC ACID, AND ESTERS THEREOF, ETHYLENE-DIAMINETETRAACETIC ACID AND ITS SODIUM AND CALCIUM SALTS; AND (C) ABOUT 0.1 TO 5% BY WEIGHT OF THE COMPOSITION OF A COMPOUND FROM THE CLASS CONSISTING OF POLYDIMETHYL AND POLYDIETHYL SILOXANE HAVING A VISCOSITY OF 100 TO 100,000 CENTISTOKES AT 100*F.

Cl. 426-181 No Drawing. 24 Pages Specification An antioxidant composition for oils and fats particularly those used for frying is retained in the oil or fat even after many fryings at high temperatures. Included in the composition are (A) about 60 to 99% by weight of the composition of an antioxidant selected from the group consisting of mono-tertiary-butylhydroquinone, a gallic acid ester selected from propyl, octyl or dodecyl gallates; and blends of these antixodiants with butylated hydroxyam'sole and bntylated hydroxytoluene;

(B) 0 to 34% by weight of the composition of an organic acid synergist selected from the group consisting of citric acid, ascorbic acid, tartaric acid, furnaric acid, and esters thereof, ethylene-diaminetetraacetic acid and its sodium and calcium salts; and

(C) about 0.1 to 5% by weight of the composition of a compound from the class consisting of polydimethyl and polydiethyl siloxane having a viscosity of 100 to 100,000 centistokes at 100 F.
